4.5.6Power
The Baseboard supplies 12V and 3.3V power to the Memory Board. The Memory Board has on board regulators to generate 1.8V, 1.5V and 0.9V. The XMB requires 1.5V and 1.8V, the DIMMs
require 1.8V and DIMM termination requires 0.9V. The I2C devices use the 3.3Vstby from the Mainboard.
4.6Memory Hot Plug
4.6.1Prerequisite for Memory Hot Plug
Before performing a Memory Board hot remove or add, ensure the system BIOS is configured to support this operation, and the operating system supports this capability. See Chapter 10.1 for more information about memory modes and their support for memory hot plug operations.
4.6.2Memory Board Hot Remove
If the board is already powered on, the following steps are required to ensure proper removal:
1.Press the attention button. The attention LED will begin flashing to indicate that the BIOS is preparing the board for a hot remove. The System BIOS will copy the data off the board and the attention LED will continue to flash as this operation completes.
2.When the attention LED stops flashing and turns off and the power LED has turned off, disengage the retention latch and remove the Memory Board. If the power LED does not turn off, the memory configuration may not support memory hot plug events, see Section 10.1 for more information.
4.6.3Memory Board Hot Add
1.Plug the Memory Board into the Mainboard and engage the retention latch.
2.Press the attention button to alert the BIOS that a Memory Board has been added to the system. The BIOS will prepare the board for operation and, depending on the memory mode, may blink the power LED to indicate the board is not yet available. When the power LED is on the board is in use. If the power LED does not stay solid green, the BIOS has rejected the Memory Board, see Section 10.1 for more information.
